310 The amounts of amount that Kylie and Elijah had left were the same. Make the numerators the same.
710 of Kylie's amount =
310 of Elijah's amount
2130 of Kylie's amount =
2170 of Elijah's amount
Amount that Kylie had = 30 u
30% of the amount that Kylie had
= 30% x 30 u
=
30100 x 30 u
= 9 u
Difference between Elijah's amount and 30% of Kylie's amount
= 70 u - 9 u
= 61 u
61 u = 3050
1 u = 3050 ÷ 61 = 50
Amount that Elijah had at first
= 70 u
= 70 x 50
= $3500
Answer(s): $3500
